If you're preparing a Ph. D. thesis, the literature review is usually one chapter (eight to ten thousand words), however this might vary greatly depending on your subject. Consult your boss! If they don't know how long it should be, there's no way for us to guess.
The literature review covers the research done on your topic up until now. It discusses what others have already found out about your topic, including any theories or models that have been proposed to explain its nature and causes. The goal is to provide a comprehensive overview of the state of the art on your topic, as well as ideas for future directions that may not have been considered yet.
In general, a good literature review contains the following elements:
A concise introduction to the topic being studied. This section aims to give the reader a clear understanding of what the study is all about. It may include a short description of the problem, a definition of the term used throughout the paper, as well as a survey of related work. You can find more information about introductions here.
A detailed analysis of the relevant studies. Start with the most recent studies first, then move back in time as needed. Explain why previous work is not applicable to your topic, even if it was done on subjects very close to yours.
The review is often a complete chapter (at least 20 pages) in a thesis or dissertation, however it may simply be a few pages in an assignment. A literature review can be organized and structured in a variety of ways. The most common methods are systematic or narrative. Systematic reviews use a set protocol to identify, select, and analyze studies in the field. Narrative reviews use a problem-based approach that includes reading as well as analyzing existing literature.
In addition to or instead of using a formal method, a reviewer can also use a subjective analysis to identify relevant literature. For example, a reviewer could read all the articles on a particular topic to get an idea of what others have to say about it. Then, they could refer back to these sources to find additional works that might not have been identified by a computer search engine. Subjective analyses help reviewers think beyond the results of their search engines but should only be used if there is no other way to identify relevant literature.
Literature reviews are usually required when doing research for a paper or project. They help readers understand how previous researchers have dealt with similar topics or problems. In addition, they provide evidence of what questions have been asked before and what answers have been found to be effective. Finally, they can help readers understand why some researchers study certain topics while others focus on different ones.
A literary review's length varies according on its objective and readership. Generally, the first section of the paper is a summary of the relevant literature, followed by a discussion of the contributions made by each study and finally a conclusion highlighting the main ideas developed throughout the paper.
In addition to being aware of one's objectives when writing a literature review, we must also be aware of our readers' expectations. If you are writing for an audience that has not been given any specific instructions about what a literature review should include, then they will expect you to summarize the relevant literature and discuss how the different studies contribute to your overall argument or idea. However, if your audience expects you to provide a detailed analysis of each study, then they will not be satisfied with a short literature review.
In general, a literature review should be 20 pages long including references. This gives you enough space to discuss several topics within the literature and give examples from various sources. When writing a literature review, it is important to be clear and concise without skipping over any details that could help your reader understand your argument better. Also, as you develop your own ideas about the topic, make sure to include those too!
A literature review is typically included as a portion or component of a dissertation, research project, or long article. It can, however, be assigned and graded as a stand-alone piece of work. The purpose of a literature review is to summarize the existing knowledge on a topic by discussing and interpreting the most important studies about this subject.
As with any other academic work, the quality of the writing and the argumentation in a literature review should be excellent. Authors must clearly explain their interpretations of the results of the studies they discuss. They should also provide their own conclusions based on what they have found in the literature. Finally, a literature review must not only summarize the work of others but also present ideas that have not been considered before. An original contribution to the field is therefore always ensured even if it involves using information from previously published works.
Literature reviews are used when there is no existing research on a particular topic. In these cases, authors have to identify all the studies that might be relevant and then choose the best ones to include in their summary or analysis. This process may require some creative thinking since it is impossible to cover every relevant study.
Once the literature review has been written, a professional writer should carefully read it and make any necessary corrections before submitting it for approval.
In the absence of particular directions, a common rule of thumb is that the length of your literature review should be commensurate to the length of your overall report. If your work is 15 pages lengthy, 2-3 pages for the literature review may adequate. However, if you have 20 pages worth of findings to communicate, then a 1 page literature review would be insufficient.
A shorter literature review can be used when the main focus of your paper is not the literature but rather an analysis of its own data or original research conducted by others. In this case, a thorough review of the relevant literature is unnecessary since you are already presenting evidence from your study.
Longer reviews are required when the literature review plays an important role in advancing our understanding of the topic at hand. For example, if you were writing on workplace bullying and wanted to include a review of the relevant research, then you would need to provide a comprehensive account of the field. Likewise, if you were investigating the effectiveness of training programs on employee well-being, then it would be important to describe previous studies and what they found so that we can make progress in the same direction.
In addition to being sufficient in length, reviews must also accurately represent the state of the art in their fields. This means that you need to include only recent and relevant research.
